Evaluating Expressions

What are the steps you need to take in order to evaluate expressions?  (notes)

Expressions

Evaluate the following expression:


4x - y + 2y - x     When x = -8   and y = -5

Evaluating Expressions

Evaluate the following expression:

-4p2 + 5q - 7    

When p = -3 and q = -8

Evaluating Expressions

Evaluate the following expressions and then simplify:

#1.   ab - 7 + a      when a = 10   and    b = -2

#2.   2x + 5y          when x = -3   and    y = -2

Evaluating Expressions

Simplify:

3x + 2 - y      when x = -2  and y = 4


x/y - x + y      when x = 6   and y = 3
